Interesting. I was also wondering about this; how the kettle knows what the boiling point is, since it cannot just measure temperature, because it would boil out the water in the mountains. I thought there is electronics which simply detects not only absolute temperature, but also change. Once the temperature stops changing and is around 100 degrees, it will stop.
